Bio Units

Designed to co-ordinate with the Solum Range of drum filters, they utilise the same curved base configuration to reduce dirt traps and can be installed either singly or in multiples, in parallel.

The Design also causes the bio media to more easily circulate, thereby increasing the amount of bio media your water touches as it travels through the unit.

Can be installed in multiple configurations to make best use of the space you have available.
